We're at the peak of flu season and you might be putting yourself at risk without even realizing it.

Here's what might be getting you sick:

  1. Washing your hands incorrectly. Washing your hands is one of the best defenses against the flu, but you've gotta do it right. That means washing with soap and warm water for 20 seconds or more. Even though that doesn't sound like a long time, less than half of people actually do it.
    One way to keep yourself accountable is to sing "Happy Birthday" in your head twice while washing your hands, that should get you close to 20 seconds.
  2. Relying on antibacterial hand gel. First, check the ingredients in your hand sanitizer, it should contain 60% to 95% alcohol, ethanol, or isopropanol, to work best. It doesn't replace old-fashioned hand-washing, which is always better.
  3. Hitting the gym. It's true that exercising does keep your immune system strong against the flu. The gym is also a great place to pick up viruses, like from the sweaty treadmill, weight benches, and the locker room.
  4. Worrying too much. Just worrying about getting sick can weaken your immune system and make you more likely to get sick. Try to keep things in perspective.
